# Claro 1.0 - Release Candidate
# Claro v1.17.26
Beginner-friendly programming for everyone.
<img src="assets/Claro_Logo.jpg" alt="Claro logo" width="160">
Claro is a simple, readable programming language designed for:
Claro is a small, readable scripting language designed to help beginners — especially learners with learning disabilities — learn programming without being overwhelmed by punctuation-heavy syntax.
- new programmers
- classrooms
- people with learning differences
Claro stays plain-text first: simple enough to start with `SET name "Jon"`, but able to grow into stronger typed scripts, objects, packages, graphics, networking, and tooling over the v1 line.
It uses clear, English-style commands and friendly error messages so you can focus on learning and creating.
## Status
---
**Current release:** Claro v1.17.26
## Repository
Validated in this package:
https://codeberg.org/RayPals/Claro
```bash
./claro --version
# Claro v1.17.26
---
./claro test
# PASS: 0 failure(s)
## Features
./claro validate
# Validation passed. Claro v1.17.26 networking reliability is ready for use.
```
- Easy to read and write
- English-like syntax
- Friendly error messages
- Simple loops and decisions
- Reusable functions (`TEACH`, `CALL`, `RETURN`)
- Beginner game objects (sprites)
- Classroom-safe mode
- Portable — no installation required
## Beginner-first syntax
---
Claro accepts both the sentence-like style and the shorter simple style:
## Running Claro
```claro
SET name TO "Jon"
SET name "Jon"
SET city to "Edmonton"
Interactive mode:
ASK "What is your name?" name
SAY "Hello " + name
claro
IF name = "Jon"
SAY "Nice name!"
END
```
Run a program:
Older forms such as `ASK "Name?" AS name`, `ENDIF`, `DONE`, and `LEARNED` still work so older Claro examples do not break.
claro program.claro
## Simple functions
Classroom safe mode:
```claro
TEACH greet name
SAY "Hello " + name
END
claro --classroom program.claro
DO greet "Jon"
```
---
Older function syntax still works:
## Your First Program
```claro
TEACH greet TAKES name
SAY "Hello " + name
LEARNED
Create a file called `hello.claro`
CALL greet WITH "Jon"
```
SAY "Hello, world!"
## Objects and classes
Run it:
Classes can have typed fields and simple methods.
claro examples/hello.claro
```claro
CLASS Player
HAS name TEXT
HAS score NUMBER
---
TEACH show
SAY name
SAY score
END
## Core Commands
TEACH add points
SET score score + points
END
END
SAY — show output
ASK — get input
SET — store data
IF — make decisions
DO — repeat
WAIT — pause
NEW Player player
SET player.name "Jon"
SET player.score 10
---
DO player.show
DO player.add 5
SAY player.score
```
## Functions with TEACH
Object helper commands:
TEACH add TAKES a, b
RETURN a + b
LEARNED
```claro
OBJECT CLASS player AS kind
OBJECT FIELDS player AS fields
```
CALL add WITH 2, 3
SAY RESULT
## Static type safety
---
Beginners can still write the simplest form:
## Sprites
```claro
SET name "Jon"
```
CREATE SPRITE player
MOVE SPRITE player TO 10 5
SHOW SPRITE player
HIDE SPRITE player
When learners are ready, Claro can protect variables with plain-text types:
---
```claro
SET score NUMBER 10
SET name TEXT "Jon"
SET ready YESNO YES
## Building from Source
TYPE OF score AS kind
SAY kind
Linux / macOS:
CHECK TYPE score IS NUMBER
```
gcc src/claro.c -O2 -o claro
## Project and package workflow
Windows (MinGW):
v1.17.26 hardens Claro's project/package workflow.
gcc src/claro.c -O2 -o claro.exe
Create a starter project:
---
```bash
claro new MyProject
cd MyProject
claro run
```
## Contributing
Manage packages:
https://codeberg.org/RayPals/Claro/issues
```bash
claro package init
claro package add text
claro package add sdl
claro package list
claro package remove text
claro package doctor
claro package lock
```
---
Claro now creates and maintains:
## License
```text
claro.project
claro.lock
packages/
```
MIT
Package names are checked so unsafe names such as `../bad` are rejected.
## Networking
v1.17.26 adds safer beginner networking commands with offline `claro://` test URLs.
```claro
HTTP CHECK "claro://hello" AS safe
SAY safe
HTTP GET "claro://hello" AS page STATUS status
SAY page
SAY status
HTTP SAVE "claro://json" TO "network_demo.json" AS saveStatus
SAY saveStatus
```
The latest HTTP status is also stored in `LASTHTTP`. Real `http://` and `https://` requests use `curl` when available, while `claro://` works offline for lessons and tests.
## Useful commands
```bash
claro help
claro --version
claro test
claro validate
claro doctor
claro examples
claro check examples/quiz.claro
claro typecheck examples/type_hardening.claro
claro fmt examples/quiz.claro
claro repl
claro new MyProject
claro run
claro package init
claro package add text
claro package list
claro package doctor
claro ide
```
## Good first scripts
```bash
./claro lessons/01_hello.claro
./claro examples/quiz.claro
./claro examples/simple_functions.claro
./claro examples/objects_classes.claro
./claro examples/text_polish.claro
./claro examples/networking.claro
```
## Release direction
Claro should remain in the `v1.xx.yy` line for normal development. A future Claro v2 should mean a full rewrite years later, not an ordinary feature update.
